	Mechanical work - Wikipedia, the free encyclopedia
		Work (abbreviated W) is the energy transferred by a force to a moving object.
		The SI derived unit of work is the joule (J), which is defined as the work done by a force of one newton acting over a distance of one metre.
		Forms of work that are not evidently mechanical, such as electrical work, can be considered as special cases of this principle; for instance, in the case of electricity, work is done on charged particles moving through a medium.

	AllRefer.com - work (Physics) - Encyclopedia
		When there is no friction and a force acts on a body, the work done by the force is equal to the increase of the kinetic and potential energy of the body, since all the energy expended by the agency exerting the force must be gained by the body.
		The efficiency of a machine, which is defined as the ratio of the work output to the work input, is always less than one, since some of the input is invariably wasted in overcoming friction.
		Some of the units used to measure work are the foot-pound, the erg, and the joule.

	Work - Wikipedia, the free encyclopedia
		In project management, work is the effort applied to produce a deliverable or accomplish a task.
		Commonly, work is effort expended by people in the home, school, or employment, or, by extension, one's place of employment or employer.
		In the fine arts, a work is a creation, such as a song or a painting.

	Definition and Mathematics of Work (Site not responding. Last check: 2007-10-07)
		In physics, work is defined as a force acting upon an object to cause a displacement.
		When determining the measure of the angle in the work equation, it is important to recognize that the angle has a precise definition - it is the angle between the force and the displacement vector.
		In summary, work is a force acting upon an object to cause a displacement.

	SparkNotes: SAT Physics: Work
		Work is not done whenever a force is exerted, and there are certain cases in which we might think that a great deal of work is being done, but in fact no work is done at all.
		The work done in a force vs. displacement graph is equal to the area between the graph and the x-axis during the same interval.
		The work done on the box is equal to the area of the shaded region in the figure above, or the area of a rectangle of width 2 and height 4 plus the area of a right triangle of base 2 and height 2.

		Three students were intended physics majors, 12 took the course to fulfill the requirement for another science major or pre-medicine, 3 were fulfilling a distribution requirement, and 2 were taking the course for other reasons.
		The remaining students did change their images of physics careers, but the images encompassed the five main career areas, described materials at the workplace (for example, levers and lasers), or commented on the nature of physics work (for example, a job that does not have regular 9 to 5 hours).

	Work
		In almost all cases considered when studying mechanical forms of energy, when work is done on an object a force is applied to the object, and the object is displaced while this force is acting upon it.
		The amount of work is calculated by multiplying the force times the displacement.
		Now, since work is calculated as the product of force times displacement, many different combinations of forces and displacements could yield the same work, or the same energy transfer.

		The Royal Swedish Academy of Sciences named MIT Physics Professor Wolfgang Ketterle as one of the 2001 Nobel Prize laureates in Physics on Tuesday for his work in experimentally discovering Bose-Einstein condensates (BEC), a new state of matter.
		Essentially, Einstein predicted that if a gas of certain types of atoms are cooled to a very low temperature, all the atoms will suddenly gather in the lowest possible energy state to form a new state of matter.
		“The primary impact of this discovery is that it is one of the few developments in physics recently that has unified the different subfields of atomic physics and condensed matter physics,” said Professor David E. Pritchard.
